Common questions

Do I need an account?
No. There is no sign-up and no login. Open the app and everything is available immediately.
Where is my data stored?
On your iPhone. Your weight, steps, runs, and check-ins are saved locally on the device and are never sent to us or anyone else.
What happens if I delete the app?
Because everything is stored on the device, deleting the app deletes your logged data. There is no cloud backup to restore from, so export or write down anything you want to keep first.
Why does it ask for location?
Only to track a run with GPS on the Run tab, and only while the app is open. The rest of the app works fully if you decline.
Why does it ask for photo access?
Only to save a run share image to your photo library when you choose to. It is add-only; the app cannot read your existing photos.
How does the weekly check-in decide what to change?
It compares this week's average weight to last week's, factors in your waist measurement if you entered one and whether gym strength went up, held, or dropped, then recommends one adjustment. One at a time is deliberate — changing several things at once tells you nothing about which worked.
Is this medical advice?
No. 90 Day Shred is general fitness and nutrition information, not medical advice. Consult a qualified health professional before starting any nutrition or training program, particularly if you have an existing health condition.
